‘Les Incas’ is the second of three adjacent episodes from ‘Il était une fois… l’espace’ that are more educational than entertaining, and which have nothing to do with the main story.

This time, Pierrot, Psi, Metro, Legros and Maestro visit a planet on which the people live like Incas. Thus Barillé is able to tell us about the Inca society, which he does at great lengths. Only after three-fifths a story kicks in, when the friendly Inca society is about to be attacked by an unseen neighboring people, and our heroes refuse to help them in the battle. The Inca’s own Teigneux and Nabot trick our heroes to get hold of their weapons, but Metro once again saves the day.

This slow and tiresome episode also features an Erich von Däniken-like story about earlier visitors, Astronauts, who turned into Gods, just like in ‘La planète Mytho‘.
